When installing the Willoughby Industries' Top-4 Overfl ow Preventer w/ Manual Reset:
Before step 1 of the installation instructions, ensure that rough-ins are in the correct location.
The valve assembly, including the spray head, MUST NOT BE connected until after
all lines have been fl ushed to remove the small particles of debris that are inherent
with new construction projects and all chemicals that are used in fl ushing are purged
from the system.
Chemicals used in fl ushing plumbing systems can attack the internal components of
the valve and spray head and severely damage them, so any fl ushing of the system
must be followed by a full fl ushing with pure water to clear any harsh chemicals
remaining in the system. Debris in the system if allowed to enter the valve assembly
and spray head can cause poor performance or outright failure.
Again DO NOT attempt to connect the valve assembly and spray head until after all
fl ushing is complete and pure water is the only media that will be passing through the
system. Damage to the valve assembly or spray head caused by harsh chemicals or
debris will not be covered by the manufacturer's warranty.
Check Rough-In location PRIOR to installation
Flush lines thoroughly PRIOR to hook-up

Installation Instructions
1.) Mount TOP-4 valve with reset button #980401T to the fl ush valve's vacuum breaker tube using
the included clamp. Tighten securely, but noy to the point of deforming the vacuum breaker tube.
Ensure the bracket is mounted on the vacuum breaker tube such that the rubber tee fi tting is
facing downward (see drawing on reverse side).
2.) Connect the two (2) pieces of the tubing th the rubber tee fi tting.
3.) The natural color LDPE tubing #600471 (2 pieces at 36" long) should be connected to the s/s
vacuum generator and bowl sensor. This connection is made with a push-type union connector
#320446 & #320448 (see drawing on reverse side).
Do not shorten this piece of tubing.
4.) The TOP-4 valve is installed in the hydraulic fl ush valve's low pressure line. This line is identifi ed
with a letter "L" on a Sloan® fl ush valve and pushbutton for the fl ush valve. After this line has been
connected between the fl ush valve and the pushbutton, cut it at a location that will allow both of
the cut ends to reach the TOP-4 valve. The tube that connects the high pressure (letter "O" on a
Sloan® valve) fi ttings on the fl ush valve and pushbutton will remain unchanged.
5.) The line from the fl ush valve (letter "L" on a Sloan® valve) connects to the elbow tube fi tting on the
top of the TOP-4 valve and the line from the fl ush valve pushbutton (letter "L" on a Sloan® valve)
connects to the straight fi tting on the bottom of the TOP-4 valve (see drawing on reverse side).
6.) Ensure all connections are tight to complete the installation.
Note: if the plastic fi ttings are taken apart for any reason, use ONLY thread tape on the plastic
threads to reseal them. DO NOT USE ANY OTHER THREAD SEALERS OR THREAD
LOCKERS ON THE PLASTIC THREADS. Thread sealers and thread lockers will attack the black
plastic parts. If you have any questions, contact Willoughby Industries at: (317) 638-2381.
